Tapsigner

Description

The TapSigner card is a new-generation Bitcoin storage device developed by Coinkite. Designed as a compact NFC card, this device allows users to securely store and sign Bitcoin transactions with one touch. It’s an ideal solution for beginners getting started with self-custody of digital assets or for building professional multisig strategies.

BitcoinVN Shop is currently the official distributor of TapSigner in Vietnam.

Why is TapSigner favored by traders?

Wireless communication via NFC 

Unlike traditional hardware wallets that need USB connections, TapSigner works via NFC (Near-Field Communication) – a short-range wireless protocol, similar to Apple Pay or Google Pay. This allows you to verify transactions by simply tapping the card on your device. Owning a TapSigner card increases convenience and reduces vulnerabilities associated with physical ports.

You have full control over your private key

TapSigner does not come with a pre-made private key from the manufacturer. Users create the key directly on the device during the first setup, ensuring complete control and that no one else (not even Coinkite) can access or copy it.

Authentication according to PSBT (Partially Signed Bitcoin Transactions) standard

The TapSigner card supports the PSBT standard – a safe and flexible way to sign Bitcoin transactions. This allows you to easily work with software wallets like Nunchuk, Sparrow, or multisig systems. PSBT makes transaction signing clear, secure, and compliant with a standard process, reducing risks during operations.

Optimized for Multisig – Compatible with Nunchuk & Sparrow Wallet 

TapSigner works very well in multisig wallet setups. It’s an ideal choice for anyone who wants to build a secure, distributed Bitcoin storage system that doesn’t rely on a single device.
